Abstract

The invention discloses a multi-functional valve with inflation, pressure relief, isolation and communication functions. The multi-functional valve comprises a valve body, a valve core and a communication valve body, the valve body comprises an inner valve body and an outer valve body, a communication pipe is arranged below the inner valve body, the valve core comprises a valve core body, a flangeis arranged at one end of the valve core body, and a communication pipe connecting end is arranged at the other end of the valve core body. A valve deck is arranged on the upper part of the communication valve body, a rotating handle is arranged between the communication valve body and the valve core, the rotating handle and the communication valve body are connected through threads, the rotatinghandle and the communication valve body are connected by arranging a screw, the function of inflating a plurality of air chambers is achieved, and through the arrangement of the communication valve body and a communication valve core, the functions of isolation and air relief are realized.

Description

technical field [0001] The invention belongs to the field of valves, and in particular relates to a multifunctional valve with the functions of inflation, pressure relief, isolation and communication. Background technique [0002] Inflatable rubber boats have the characteristics of small storage volume, light weight, convenient movement, low price, and wide range of use environments, and have been widely used by all walks of life. Especially in rescue and disaster relief, beach landing and other aspects play an important role. [0003] Conventional inflatable rubber boats generally adopt a multi-air chamber structure, and each air chamber needs to be equipped with an inflation valve and a safety relief valve. When inflating and deflating, it is necessary to inflate the air chambers one by one. It takes a long time to inflate, and it is necessary to manually switch the inflatable position continuously, or to cooperate with multiple people to operate. When the inflation pre...
